Before the panama canal people from East coast of America who wanted to go to Asia had to either sail around south America which took months or sail towards Asia and go around Africa which took even longer.

The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The Great Britain gained territories in the North American, but disputes about policies and paying war's expenses led to colonial discontent. Taxation was created to pay back the debts. Stamp Act, Tea Act and Townsend Act were introduced. This ultimately led to the American Revolution.
